  • the critical angle in the above enumeration is a function of the relative indices of refraction of the two materials that comprises a given interface. Snell’s Law can be used to compute the critical angle.
  • the relative indices of refraction of various materials are available in published reference tables, such as by Sultanova et al. in Acta Physica Polonica A, volume 116, 2009, pages 585-587. Or the relative indices of refraction can be measured for novel materials.

  • Each subunit includes a first surface through which light from at least one LED enters the light-transmitting body; a second surface through which light exits the light-transmitting body; and a core coupled to both the first surface and the second surface, such that light propagates through the core between the first surface and the second surface.
  • the shapes, in concert, are arranged such that a recursive relation on indices of the plurality of light-transmitting bodies is applied, such that any second surface of a light-transmitting body covers from above one and only one first surface and a segment of the core of another light-transmitting body, and that any first surface and the segment of the core of a light-transmitting body is disposed in a cavity underneath one and only one second surface of another light-transmitting body.
  • the subunits are placed adjacent to each other, such that the elongated segment of a first subunit is placed underneath the surface facing the interior side 1103 of a second adjacent subunit, where that placement is possible due to the aforementioned tilting of the subunits, see FIG. 2C.
  • the elongated segment that is covered is therefore concealed from a human observer when the exterior surfaces 1102 of the assembled subunits are viewed from any distance and from a direction at an angle 1106, such as 0, 5, 30, 45, 80 or 89 degrees, relative to the normal vector of the larger square surface.
  • the construction thus obtained conceals from the human observer the electronics and the LEDs, which may reside within the concealed cavity. There may be other components stored therein. Accordingly, the LED, the first surfaces and segments of the core of the plurality of light-transmitting bodies are concealed as the luminaire is electrically powered and is viewed from an acute angle relative the normal vector of any of the second surfaces of the light-transmitting bodies of the plurality of light-transmitting bodies.

  • the entire assembled unit with concealed cavities can be manufactured from one injection mold or a single instance of three-dimensional printing.
  • the assembly of the subunits can be done by attaching them with glue, screws, clips or some other means at the interior side to a frame or foundation.
  • Other methods of assembling the four subunits and the LEDs in a configuration as specified above and illustrated in FIGS. 2A-2C can be contemplated.
  • the sharp angle is removed by the smooth continuous joining of the depressed section of the panel, where light injection is done 1433, to the section of the panel with an interface to the surrounding 1102, see FIG. 3C and FIG. 3D.
  • the segment of the core 1421 between these two parts of the panel can be any of a variety of shapes, such as but not limited to polygonal, straight, sigmoidal or some general curve moving upwards from one end to the other.
  • Each surface element of the large exterior surface 1102 can therefore be reached by light rays or quanta that have not necessarily undergone any major redirection by reflection or scattering, which implies there are more paths of that kind.
  • the light rays or quanta propagate through the core of the light-transmitting body with little or no loss because they mostly reflect against the interior interface by the physical mechanism of internal reflection, as described above.
  • the lesser the bending or curvature of the segment of the core either the relative height difference between the exterior surface 1102 and the concealed parts where the LEDs 1401 and injection surface 1433 are, is smaller, or the LEDs 1401 and injection surface 1433 of the given panel is farther removed from the part of the panel with the exterior surface 1102 to the surrounding. Both variations can further constrain the mechanical assembly of components of the luminaire.
  • the continuous joining of the depressed part for light injection can be combined with the feature of an interior interface 1103 at an angle, see FIG. 3D. This has the same effect on the injected light rays or quanta as a tapered interior interface has for the other embodiments described above with an interior interface like that.
  • the method by which the shape of the segment of the core 1421 and the shape and angle of the injection surfaces are obtained can be as follows.
  • the degree of mixing that is required in order to meet specifications with respect to the luminous emittance from the exterior surface 1102 imply for a certain material specification, a minimum distance of propagation that is required between the injection surface 1433 and the part of the panel, that is visible to the human observer, and that receives an appreciable amount of light rays or quanta from said injection surface.
  • An injection surface at an angle means the distance of propagation is greater than had the light been injected at a surface orthogonal to the shortest distance between the two ends of the segment of the core.
  • the angle of the injection surface 1433 affects which surface elements 1201 of the exterior surface 1102 that receives the most light from which LED source.
  • the sections of the panel subunit which are relatively thin for one or several reasons enumerated in the previous paragraph, can require more light directed towards it, since light rays or quanta are at a higher probability of exiting the panel on their path to said sections.
  • An optical output that meets the specifications by the architectural or interior design application can be obtained by the simultaneous consideration of the above structural factors, employing means, such as but not limited to, optical computer simulations, prototyping and laboratory testing.
  • a light-transmitting body design is obtained, including the shape of the segment of the core 1421 and the placement of the injection surface 1433.
  • the optical design is successful in spreading out the light and hence to create a luminaire of a luminous emittance that can be directly viewed by a human observer without unpleasant experiences of glare or other undesired light qualities.
  • FIGS. 4A-4C a small structure without optical function is shown 1439. These two small pegs can help in the assembly of the luminaire.
  • the tolerance for the overlapping of panel subunits can be small, and therefore it can be helpful to include a small structure to guide the fitting of subunits to a complementary indentation in an interior panel of the luminaire.
  • FIGS. 3A-3D and FIGS. 4A-4C and FIG. 5 is that as light rays or quanta are injected into an optical material through a surface, which is situated below the exterior surface of the panel subunit, said light rays or quanta are guided through a section of some shape and material composition in which the light mixes, such that the degree of light concentration in any surface element is reduced below a specified threshold relative the light concentration at the LED sources, while all or some of said light rays or quanta propagate into the section of the panel subunit with an exterior surface, through which the light can exit by one or a plurality of optical mechanisms and thus contribute to the illumination of the room or space.
  • embodiments of the innovation has so far been described in terms of one larger square apparently divided, or tessellated, into four smaller and partially overlapping congruent squares.
  • Other embodiments of the innovation can be contemplated, which employs the disclosed method of constructing subunits and installing these in a particular geometric relation to each other in order to create a thin luminaire panel of some shape with light output less concentrated than a threshold, without a frame or other dark, or non-radiant, surface elements.
  • All of these contemplated embodiments can use the method of bent or curved subunit structures in order to create the concealed cavity, in which to house the LEDs and the segment of the core of the light-transmitting body in which adequate light mixing is attained.
  • At least one segment of the core of the light-transmitting body covers from above at least one cavity in which the LED, the first surface and the opaque layer is contained, and at least one segment of the second surface is disposed above said segment of the core such that, the LED, the opaque layer, the plurality of first surfaces are concealed as the luminaire is electrically powered and is viewed from an acute angle relative the normal vector of the second surface.
  • Some of the light rays or quanta 1494 that are injected into the panel material can propagate to an edge of the luminaire without being redirected by reflection at the interior surface, internal reflection, or scattering, as described above.
  • a reflective surface orthogonal to the opaque cover surface can be added to an edge of the light-transmitting body 1403. Light rays or quanta that are reflected at this edge can propagate back through the core towards the LED sources 1401 and the cover surface 1402. Some of these light rays or quanta can propagate through the segment of the core above the opaque cover surface.
  • Light rays or quanta that propagate within the segment of the core of the light-transmitting body above the opaque cover surface 1402 can be redirected by a microstructure (e.g., the opaque cover surface 1402, in an embodiment, has a microstructure deposited thereon) .
  • a microstructure e.g., the opaque cover surface 1402, in an embodiment, has a microstructure deposited thereon.
  • Optical events as described above can lead to that these light rays or quanta exit the panel material through the exterior surface.
  • the illustrative embodiment shown in FIG. 8 contains additional parts, such as the mechanical support on the interior side, like a back-tray 5002 and a mechanical mount 5001 to attach the luminaire to a wall, ceiling or other surface in the room.

  • the illustration also includes an additional layer of optical transformation by a diffuser 5111, which also provides mechanical support.
  • the optical aspects of this part is a continuation of the main optical material 1111, and can therefore in all descriptions be treated as part of the light-transmitting body.
  • the particular embodiment shown in FIG. 8 has therefore divided the functionality of optical transformations into two parts joined upon assembly of the luminaire, where one part in addition to optical functionality also serves a mechanical function for the safe operation of the luminaire.
  • the reflection surface and the distribution of microstructures have to be re-optimized for the new geometries.
  • concentrated light rays or quanta are emitted from one or a plurality of LEDs, located in a cavity beneath the light-transmitting body from the perspective of the human observer, where the LED or LEDs are covered by an opaque surface, and the opaque surface is cloaked in light that can have propagated to the surface element above the opaque surface through a plurality of reflections, scattering and other optical events within the light-transmitting body, in particular redirection into the segment of the core above the opaque surface.

That is: (1) The light rays or quanta can collide with a Titanium Oxide particle, surface imperfections or other microstructure part of a diffuser, upon which the light scatters in an appreciably random manner within the material. (2) The light rays or quanta can reach the interface between the panel material and the surrounding space at an angle less than a critical angle, and then exit the panel into the surrounding.
